14The following appeared in a memo from the owner of Green Thumb Gardening Center, a small business serving a suburban town.

"There is evidence that consumers are becoming more and more interested in growing their own vegetables. A national survey conducted last month indicated that many consumers were dissatisfied with the quality of fresh vegetables available in supermarkets. And locally, the gardening magazine Great Gardens has sold out at the Village News stand three months in a row. Thus, we at Green Thumb Gardening Center can increase our profits by greatly expanding the variety of vegetable seeds we stock for gardeners this coming spring."

 

1.一个全国性调查的结果并不一定和一个城郊地区的情况一致。

2.杂志连续三个月售罄并不能代表人们对于自己种植蔬菜就会越来越感兴趣，首先，这个杂志的发行量可能很小，或者杂志，这样的话售罄并不能说明什么问题。其次也没具体说明这个杂志的内容，有可能人们买这本杂志的目的并不是为了种菜，或者这本杂志里面关于种蔬菜的内容很少。

3.即使很多消费者对于超市上供应的新鲜蔬菜质量不满意，也并不能说明人们就会自己选择去中蔬菜，这将会浪费大量的时间。

4.即便人们打算自己种植蔬菜，GTGC通过大量增加蔬菜种子的种类也不一定能够带来盈利，也许人们只对其中的少数蔬菜种子感兴趣，那么这样就会造成大量的成本增加，在可预见的时期内也许会超过盈利。
